Abstract
Description
- 1. Field of the Invention
- The present invention relates to agricultural harvesters such as combines, and, more particularly, to crop residue systems used in such combines.
- 2. Description of the Related Art
- An agricultural harvester known as a “combine” is historically termed such because it combines multiple harvesting functions with a single harvesting unit, such as picking, threshing, separating and cleaning. A combine includes a header which removes the crop from a field, and a feeder housing which transports the crop matter into a threshing rotor. The threshing rotor rotates within a perforated housing, which may be in the form of adjustable concaves and performs a threshing operation on the crop to remove the grain. Once the grain is threshed, it falls through perforations in the concaves onto a grain pan. From the grain pan, the grain is cleaned using a cleaning system, and is then transported to a grain tank onboard the combine. A cleaning fan blows air through the sieves to discharge straw, chaff and other debris toward the rear of the combine.
- During the process of harvesting, crop material other than grain (MOG) is intended to be expelled from the combine. This material is usually derived from one of two areas, the threshing rotor or the cleaning system. The material expelled from the threshing rotor is generally referred to as straw and the material expelled from the cleaning system is generally referred to as chaff. This crop residue can be dealt with in several ways, generally categorized as spread and windrowed.
- Spread refers to using a mechanical device to distribute the straw and/or chaff evenly across the width of the combine header cut width. This spread material is usually chopped to as short a length as possible so that when it is spread it will break down as quickly as possible and not interfere with tillage or seeding operations.
- Windrowing refers to the process of dropping straw directly behind the combine in a continuous stream. The purpose of doing this is usually to allow post harvest processing of the straw such as shaping it into bales. In this process, the straw is usually allowed to pass through the combine with as little interference as possible so that it remains as close as possible to its original length and condition.
- Many harvester systems have two separate spreading systems, one of which is dedicated to spreading the chaff from the cleaning system and another dedicated to spreading the straw from the rotor. These systems can be operated independent of one another. Currently, in order to windrow straw discharged from the rotor, the spreader disks normally used to spread the crop residue, must be removed from the machine and stored elsewhere since there is little available storage on the combine. Besides having to remove the disks, there is an absence of a device to slow the velocity of the straw before it hits the ground. This causes the straw to be driven into the stubble and makes it very difficult to return and pick up later. While windrowing straw, many operators prefer to spread chaff from the cleaning system which requires the use of a secondary spreader on the machine.
- What is needed in the art therefor is a system allowing for flexible distribution of crop residue from a combine without modifications to the equipment.
- The present invention provides a system for crop residue management that provides flexibility in the treatment of the material making up the crop residue.
- The invention, in one form, is a crop residue management system for flexible distribution of straw and chaff contained within the crop residue. The system includes a pair of laterally spaced spreader devices for distributing crop residue laterally. A duct is provided for directing a crop residue stream to the spreader devices in a downward direction toward the laterally spaced spreader devices and a windrow chute is displaceable between a first position in which the windrow chute is out of the crop residue stream and a second position in which it directs straw in the residue stream in a windrow behind the system and directs chaff laterally.
- In another form, the invention is an agricultural combine including a crop processing apparatus separating crop material from crop residue containing straw and chaff and for discharging crop residue therefrom in a stream. A duct is provided for directing a stream of crop residue material downstream in the combine in a generally downward direction. Laterally spaced spreader devices are positioned downstream of and below the duct for distributing crop residue laterally. A windrow chute is displaceable between a first position in which it is out of the crop residue stream permitting lateral distribution of both straw and chaff and a second position in which it directs straw in the residue stream in a windrow behind the agricultural combine and directs chaff laterally from the combine.
- The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention will be better understood by reference to the following description of embodiments of the invention taken in conjunction with the accompanying drawings, wherein:

FIG. 1 shows anagricultural combine 20 which includes the usual harvesting apparatus (not all of which is shown to facilitate an understanding of the invention). An axially orientedcrop processing system 22 receives harvested crop and a crop residue treatment anddistribution system 24 with acrop residue spreader 26 is positioned at the aft end of combine 20. The crop processing system includes a cylindricalthreshing rotor 28 that conveys a flow of crop material in a helical flow path. As the crop material is moved through theprocessing apparatus 22, the desired crop such as grain or other material is loosened and separated from crop residue such as husk and pods in a cleaning system located beneath thethreshing rotor 28. Thecrop processing system 22 includes ablower 34, schematically depicted to aid in the separation of the desired crop from the crop residue. Theblower 34 has aduct 35 extending aft in thecombine 20 towards the cleaning system and the crop residue treatment anddistribution system 24. - As pointed out, current crop residue spreading systems have required the need of in the field modifications to the harvester or added equipment to enable the flexibility of either distributing all the residue laterally or separating the straw into a windrow and the chaff laterally. In accordance with the present invention, the crop
residue spreader system 26 shown inFIGS. 2-5 is employed. - Specifically referring to
FIG. 2 , the crop residue spreader system comprises aduct 30 including atop wall 31 andsidewalls 33 to direct crop residue in an aft direction A. Aswath door 32 spans the sidewalls of theduct 30 and is pivotally mounted at 34 to be displaced between the position shown inFIG. 2 to the position shown inFIG. 3 . As shown in schematic fashion, theswath door 32 is displaced by amechanical interconnection 36 to anactuating mechanism 38, both shown in schematic fashion. Although many different elements may be used to displaceswath door 32 between its positions, the mechanism described in co-pending application entitled Linkage for Flexible Crop Residue Management System, of common assignment with the present invention, is preferred. Afixed floor 40 directs the crop residue stream towards a pair ofspreader devices 42. -
Spreader devices 42 include side-by-side disks 44 journaled for rotation about vertical axis and positioned laterally with respect to one another.Disks 44 may have a plurality ofcurved bats 46 that act like vanes to positively direct crop residue in a lateral direction. Acone 48 extends vertically upward fromdisk 44 and provides a cover for amotor 50 for each disk. The motor output shafts (not shown) cause thedisks 44 to rotate as needed. Althoughmotor 50 is illustrated as hydraulic, it may be in any one of a number of forms including mechanical interconnection to a remotely positioned motor. Rotation ofdisks 44 is set up so that when viewed from above and looking towards the front of thecombine 20, the right side disk rotates counterclockwise and the left disk rotates clockwise so that they propel crop residue between them aft and around and laterally. - In the position illustrated in
FIG. 2 , both the straw and chaff are directed aft in direction A and are deflected downward byswath door 32 to impact on thedisks 44 and curved bats 46. The rotation of thedisks 44 causes the material to be distributed aft and laterally of thecombine 20. - In accordance with the present invention, a windrow chute generally indicated at 52 is provided. Windrow chute includes a
bottom portion 54 andadjacent sidewalls 56.Bottom portion 54 is tapered in a rearward direction as particularly shown inFIG. 4 .Windrow chute 52 is displaceable between the position illustrated inFIG. 2 in which it is out of the crop residue stream and the position illustrated inFIG. 3 .Windrow chute 52 is displaced by amechanical connection 58 leading to anactuator 60. While many forms of mechanical connections and actuators may be employed for this purpose, the apparatus referred to in the above identified co-pending application is referenced and is hereby included in its entirety.Windrow chute 52 additionally includesdeflectors bottom portion 54. As particularly shown inFIG. 5 ,deflectors horizontal spreader disks 44. - In the positions shown in
FIG. 2 , thewindrow chute 52 is in its first position in which it is positioned out of the crop residue stream and theswath door 32 is in its first lowered position in which it directs all of the crop residue stream towards the spreadingdevices 26. - As shown in
FIG. 3 , theswath door 30 may be pivoted by theactuator 38 to the illustrated second position in which it is elevated and does not direct all of the crop residue stream towards the spreadingdevices 26. At the same time, theactuator 60 displaces thewindrow chute 52 to the illustrated second position in which it is in the crop residue stream. In the crop residue stream, the straw tends to be elevated and as such is directed downward to thewindrow chute 52 and the impact slows the velocity of the straw. In addition, the convergence of the windrow chute enables a better formed windrow of straw which is directed downstream of thecombine 20. At the same time, the chaff in the crop residue stream falls to theresidue spreader system 26 and thedeflectors disks 44 out of the windrow for the straw so that it does not disturb the proper positioning in the field. The chaff in this condition is spread laterally. - The
actuators windrow chute 52 in their respective positions in coordinated interdependent fashion. The actuators may be implemented in a way that it is done by control from an operator of the harvester. This feature allows minimal time to change the configuration of the harvester from a spreading operation to an operation in which straw is windrowed and chaff is spread laterally across the field. This enables significant increases in operator efficiency and harvesting effectiveness. - While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
